An American-style ring network cabinet with an insulating protective cover

technical field

The utility model relates to an American-style ring network cabinet with an insulating protective cover. It belongs to the technical field of power systems.

Background technique

In order to improve the reliability of power supply and enable users to obtain power from two directions, the power supply network is usually connected into a ring. This power supply method is called ring network power supply for short. In industrial and mining enterprises, residential quarters, ports and high-rise buildings and other AC 10kV power distribution systems, due to the small load capacity, the high-voltage circuit is usually controlled by a load switch or a vacuum contactor, and is equipped with a high-voltage fuse for protection. The system is usually powered by a ring network, and the high-voltage switchgear used is generally called the Ring Main Unit (Ring Main Unit).

The ring network cabinet is a group of high-voltage switchgear installed in the steel plate metal cabinet or made into an assembled spaced ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, low price, and Improve power supply parameters and performance and power supply security and other advantages. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. At present, ring network cabinets are generally divided into American-style ring network cabinets and European-style ring network cabinets. European-style ring network cabinets are large in size and low in cost, while American-style ring network cabinets are small in size and compact in structure. 1/3 to 1/5, beautiful appearance, although the cost is slightly higher, it has the characteristics of reliable power supply, reasonable structure, quick installation, flexibility, and convenient operation.
